SELF-ADAPTING DRIVER CIRCUIT FOR HORIZONTAL TV DEFLECTION.

A new approach for the driver circuit of the horizontal deflection in TV and monitor chassis has been realized in a low-power IC. The concept avoids the classical driver transformer and is widely independent of the different applications and deflection frequencies. The element provides an optimum charge and discharge current for the discrete power transistor and reduces the total power consumption of the deflection. Various control functions are implemented and take care of the safe operating conditions of the power element in the turn ON and OFF transient phase of the chassis. This improves the reliability of the system significantly.
